How Network-Enabled Devices Escape Your Attention: Don't Leave UPS, HVAC, and CCTV Cameras Blind and Powerless
Enterprises monitor most network-enabled devices by design. However, some devices come with networking protocols such as SNMP (Simple Network Management Protocol) disabled by default for security reasons. Some systems such as UPS (Uninterruptible Power Supplies), HVAC (Heating, Ventilation, and Air Conditioning), Physical Access Control Systems, and CCTV (Closed Circuit TV) cameras have traditionally fallen under the purview of groups such as facilities, operations, or physical security. IT may not have direct access or oversight of these systems.
Infrastructure monitoring is a necessity but it is not a “one size fits all” t-shirt. Besides the different types of protocols for monitoring different devices, there are different monitoring needs. The approach an IT admin may take to monitor their servers will be vastly different in most cases than monitoring client machines, whether they are laptops or desktops. I feel that client monitoring may sometimes get lost in the shuffle of trying to keep the servers up-and-running and optimized. Your client machines have feelings too (well maybe not feelings…) but they do have needs and also deserve some monitoring attention.
Part 2 – Using PRTG’s Custom Sensors As we saw in the first article in this series, PRTG ships with a set of pre-defined sensors for Microsoft Exchange that provide a great overview into the health and performance of an Exchange environment. But, what if we need more detail? Maybe we’re troubleshooting a specific problem, possibly an intermittent one. How can PRTG help? Unsurprisingly, PRTG has you covered (otherwise this would have been a very short article).
No Budget? No Problem! The Poor Man’s Guide to Monitoring Network Traffic with SNMP and Packet Sniffing
Legacy and modestly-priced network switches may not support flow protocols such as IPFIX, NetFlow (from Cisco, with many versions), jFlow, and sFlow. Still, administrators of older networks and those on a budget must monitor network traffic despite these limitations.
Firewalls are the quintessence of providing comprehensive security for your network infrastructure. They safeguard anything from mission-critical business processes to confidential customer data. Unforeseen interruptions in the firewall could mean big bucks, or worse. So to guarantee the safety of your network, it is important that you continuously monitor your firewalls to ensure that they run reliably and are up to date. SonicWall offers several firewalls to cover your security needs.
Unfortunately, we don’t only hire new employees all the time: for a company with 200 people it’s normal that someone occasionally leaves the company. Most leave on good terms, to take the next step in their career or to go back to university for a master’s degree. A few leave because they’re not a good fit for our corporate culture. But no matter why someone leaves Paessler, we must always ensure a clean and accurate offboarding.
Paessler is a constantly growing company. New colleagues are hired all the time, sometimes five or more in just one month. That means new accounts for our IT-systems, a workplace with all the hardware and software the new colleague needs, and many other things that can easily be overlooked. That’s why we from the Paessler IT team have created a simple process, a checklist and a couple of scripts, helping us to bring new hires in smoothly.
While Microsoft Excel was originally intended for performing financial, mathematical or statistical calculations, it’s often “abused” as a database as well. Despite ongoing controversy about whether using Excel as information storage is a good idea, it’s evident that Excel spreadsheets are used for storage in organizations of all sizes.
Mining has been going through a technological shake up in recent years. In addition to improvements in automation and safety, sophisticated new IT solutions are boosting productivity and reducing operational costs.
Encryption of the data traffic between your server and website visitors' computers has many benefits. Encryption creates security. Encryption builds trust. Encryption helps with search engine optimization (SEO) - and there are many more advantages as well. At this point, the question arises as to where I can obtain my SSL Certificate so that website visitors know that their data is indeed securely encrypted - and so that the browser doesn't send a warning.
Good news everyone! Our podcast has a new name. Please say hello to "The Geek & the Sales Guy". But that's not all: We are now available on iTunes or via our RSS feed. You can also just copy this URL and paste it into your podcast player: http://paessler.libsyn.com/rss.
What We Learned About Licensing Microsoft Products The issue of software licensing is one of the topics that our IT department must constantly address. If a new employee is hired, not only does he need a work device, but the necessary software as well. And that software must be licensed. This sounds pretty simple...
How to Avoid Heat-Related Failures and Problems If you’re running a data center / server room in your company, you will probably already be monitoring the temperature in there to avoid issues from overheating. But there are also other places and things in your office building where monitoring the temperature can help you to avoid negative effects of high temperatures.
Part 1 – Exchange Sensors Included In PRTG In this, the first in a series of articles looking at how PRTG can help Exchange Admins to manage their systems, we look at the continued popularity of email as a corporate communications tool. We’ll also see how PRTG’s pre-defined Exchange sensors can provide a great overview of system health and performance. In subsequent articles, we’ll see how custom sensors can provide even deeper insight into the many components and sub-systems that make up an Exchange infrastructure.
Google Chrome has come a long way from its humble beginnings in 2008. Today, the web browser has over 1 billion users and accounts for 75.1% of global internet usage as of March 2017. This success can be chalked up in part to its highly customizable design, simple yet incredibly handy features, and synchronization capabilities. Let's go over some of the reasons why Chrome outshines the competition.
